🐛 Bug Report

Netty at random times gets a read timeout at. This happens at different selenium commands ( for example: WebDriver.switchTo().defaultContent, WebElement.click, WebDriver.switchTo().window, WebElement.sendKeys, WebDriver.get, Alert.accept ) and at random in a quite small percentage chance (<1% test cases).

To Reproduce

I don't have specific steps to reproduce. When our CI runs our test suite of thousands of tests run, about 10 fails at random due to this timeout. I could not reproduce by doing a simple long loop with a few commands on my development workstation.

Timeout details

This timeout always occurs at:

Caused by: java.util.concurrent.TimeoutException
	at java.base/java.util.concurrent.CompletableFuture.timedGet(CompletableFuture.java:1886)
	at java.base/java.util.concurrent.CompletableFuture.get(CompletableFuture.java:2021)
	at org.asynchttpclient.netty.NettyResponseFuture.get(NettyResponseFuture.java:206)
	at org.openqa.selenium.remote.http.netty.NettyHttpHandler.makeCall(NettyHttpHandler.java:65)

I could confirm that it took 3 minutes there, confirming that it is due to the default 3 minutes read timeout the selenium configures the netty with. But the commands that are timing outs would normally run very fast, much less than one second.

Trying the code below in a method called probably thousands times by my test suite, it failed entering the catch. But after it called again driver.switchTo().defaultContent() at the end of the code below it worked. So it seems that although the read timeout happens in netty, it still works normally afterwards.

try
{
driver.switchTo().defaultContent();
}
catch (TimeoutException e)
{
// this should never happen, but started happening at random after updating to selenium 4
// output information to help troubleshoot
System.err.println("TimeoutException thrown while trying to go to defaultContent (stack below). Trying again...");
e.printStackTrace();

try
{
Thread.sleep(5000);
}
catch (InterruptedException e1)
{
}

driver.switchTo().defaultContent();
}

In this case, the stack trace got by the e.printStackTrace() above was:

Environment

OS: Docker containers inside a CentOS Browser: RemoteWebDriver using Firefox in selenium/standalone-firefox:4.0.0-beta-3-20210426 docker image. Also tried the selenium/standalone-firefox:4.0.0-beta-4-prerelease-20210527 docker image, but the same thing happened. Browser Driver version: RemoteWebDriver from selenium-java 4.0.0-beta-3 Language Bindings version: Java 4.0.0-beta-3 The RemoteWebDriver runs in a container that is running in the same docker host as the browser container. So all network between them is only logical in the same machine. Previously we were using Selenium 2.52, in the same docker host, and never happened anything similar to such timeout.

Do you have any tips about what I can try to fix it or investigate more about this?

Doing test automation on a Ember.js web application: I have a button which is covered by a <div> with a cooky notification. It looks something like this:

With Selenium 2.47.1 clicking on that button works as expected in Firefox. With Selenium 2.48.0 clicking this button does not work in Firefox, although there is no exception or error. It's like selenium thinks that the click worked properly but actually the click had no effect. Here the Robot Framework log:

The structure of HTML is something like this:

<header>...</header>
<main>
  <div>
    ::before
    <form>
      <button>Last check</button>
    </form>
  ::after
  </div>
</main>
<div>
  <div class="cookie-notification">
    ::before
    <a href="http://...">Close</a>
    ::after
  </div>
</div>

Just for comparison - executing the same click with Selenium 2.47.1 in Chrome results in a WebDriverException:

Traceback (most recent call last):

OS: Mac OS El Capitan 10.11.6

Selenium Version: 3.3.3

Browser: Firefox

Browser Version: 52.0.2 (64-bit)

Expected Behavior -

In python, the following should create a Remote driver:

from selenium import webdriver

cap = {'platform': 'ANY', 'browserName': 'firefox', 'version': '', 'marionette': True, 'javascriptEnabled': True} driver = webdriver.Remote(command_executor='http://<my_server_ip>:4444/wd/hub', desired_capabilities=cap)

(note: this works with selenium 2.53.6 with python2.7 when executed against the same server)

Actual Behavior -

Thows exception: KeyError: 'message'

When I pdb into this I see the following response from the server:

{'value': '{"status":13,"value":{"class":"java.lang.NullPointerException","stackTrace":[{"fileName":"HashMap.java","className":"java.util.HashMap","methodName":"putMapEntries","lineNumber":500},{"fileName":"HashMap.java","className":"java.util.HashMap","methodName":"putAll","lineNumber":784},{"fileName":"DesiredCapabilities.java","className":"org.openqa.selenium.remote.DesiredCapabilities","methodName":"\u003cinit\u003e","lineNumber":54},{"fileName":"RequestHandler.java","className":"org.openqa.grid.web.servlet.handler.RequestHandler","methodName":"process","lineNumber":104},{"fileName":"DriverServlet.java","className":"org.openqa.grid.web.servlet.DriverServlet","methodName":"process","lineNumber":83},{"fileName":"DriverServlet.java","className":"org.openqa.grid.web.servlet.DriverServlet","methodName":"doPost","lineNumber":67},{"fileName":"HttpServlet.java","className":"javax.servlet.http.HttpServlet","methodName":"service","lineNumber":707},{"fileName":"HttpServlet.java","className":"javax.servlet.http.HttpServlet","methodName":"service","lineNumber":790},{"fileName":"ServletHolder.java","className":"org.seleniumhq.jetty9.servlet.ServletHolder","methodName":"handle","lineNumber":841},{"fileName":"ServletHandler.java","className":"org.seleniumhq.jetty9.servlet.ServletHandler","methodName":"doHandle","lineNumber":543},{"fileName":"ScopedHandler.java","className":"org.seleniumhq.jetty9.server.handler.ScopedHandler","methodName":"nextHandle","lineNumber":188},{"fileName":"SessionHandler.java","className":"org.seleniumhq.jetty9.server.session.SessionHandler","methodName":"doHandle","lineNumber":1584},{"fileName":"ScopedHandler.java","className":"org.seleniumhq.jetty9.server.handler.ScopedHandler","methodName":"nextHandle","lineNumber":188},{"fileName":"ContextHandler.java","className":"org.seleniumhq.jetty9.server.handler.ContextHandler","methodName":"doHandle","lineNumber":1228},{"fileName":"ScopedHandler.java","className":"org.seleniumhq.jetty9.server.handler.ScopedHandler","methodName":"nextScope","lineNumber":168},{"fileName":"ServletHandler.java","className":"org.seleniumhq.jetty9.servlet.ServletHandler","methodName":"doScope","lineNumber":481},{"fileName":"SessionHandler.java","className":"org.seleniumhq.jetty9.server.session.SessionHandler","methodName":"doScope","lineNumber":1553},{"fileName":"ScopedHandler.java","className":"org.seleniumhq.jetty9.server.handler.ScopedHandler","methodName":"nextScope","lineNumber":166},{"fileName":"ContextHandler.java","className":"org.seleniumhq.jetty9.server.handler.ContextHandler","methodName":"doScope","lineNumber":1130},{"fileName":"ScopedHandler.java","className":"org.seleniumhq.jetty9.server.handler.ScopedHandler","methodName":"handle","lineNumber":141},{"fileName":"HandlerWrapper.java","className":"org.seleniumhq.jetty9.server.handler.HandlerWrapper","methodName":"handle","lineNumber":132},{"fileName":"Server.java","className":"org.seleniumhq.jetty9.server.Server","methodName":"handle","lineNumber":564},{"fileName":"HttpChannel.java","className":"org.seleniumhq.jetty9.server.HttpChannel","methodName":"handle","lineNumber":320},{"fileName":"HttpConnection.java","className":"org.seleniumhq.jetty9.server.HttpConnection","methodName":"onFillable","lineNumber":251},{"fileName":"AbstractConnection.java","className":"org.seleniumhq.jetty9.io.AbstractConnection$ReadCallback","methodName":"succeeded","lineNumber":279},{"fileName":"FillInterest.java","className":"org.seleniumhq.jetty9.io.FillInterest","methodName":"fillable","lineNumber":112},{"fileName":"ChannelEndPoint.java","className":"org.seleniumhq.jetty9.io.ChannelEndPoint$2","methodName":"run","lineNumber":124},{"fileName":"QueuedThreadPool.java","className":"org.seleniumhq.jetty9.util.thread.QueuedThreadPool","methodName":"runJob","lineNumber":672},{"fileName":"QueuedThreadPool.java","className":"org.seleniumhq.jetty9.util.thread.QueuedThreadPool$2","methodName":"run","lineNumber":590},{"fileName":"Thread.java","className":"java.lang.Thread","methodName":"run","lineNumber":745}]}}', 'status': 500}

Steps to reproduce -

Execute the above steps in python using selenium 3.3.3, firefox 52.0.2, geckodriver 0.15.0. The server is using selenium-server-standalone-3.3.1.jar on ubuntu 16.10. I'm happy to provide the ip of the server privately if it'll help.

OS:
Windows 10, Windows Server 2008 R2 Selenium Version:
WebDriver 3.4.0 Browser:
Firefox and Chrome

Browser Version:
Firefox: 53.0.3 (32 bits) Chrome: Version 59.0.3071.86 (Official Build) (64-bit)

Expected Behavior -

WebDriver suppose to close the ports after each commands sent to ChromeDriver or GeckoDriver

Actual Behavior -

WebDriver keeps the ports open until the WebDriver quit(). This caused the ports run out from the OS when I had 8 parallel tests running together without open and close ChromeDriver or FirefoxDriver.

Steps to reproduce -

Run the Selenium Tests with ChromeDriver or FirefoxDriver with any simple action, e.g. Navigate to a website. Repeat this step for 1000 time.

Open a Windows Command Prompt, type: netstat -a -b

You will find the ChromeDriver/GeckoDriver holds up about 1000 ports without releasing.

I have amended the code in OpenQA.Selenium.Remote.DriverServiceCommandExecutor.cs, line 37 old code: this(driverService, commandTimeout, true) new code: this(driverService, commandTimeout, false)

and

OpenQA.Selenium.Remote.HttpCommandExecutor.cs, line 46: old code: : this(addressOfRemoteServer, timeout, true) new code: : this(addressOfRemoteServer, timeout, false)

Retest again with the above step, we can see the ChromeDriver / Gecko Driver doesn't hold up the port any more.

It seems for HttpWebRequest object, even it is out of scope, if its' KeepAlive property is true, the .net runtime holds it until the WebDriver is quit and closed.

In theory, I can't think of HttpCommandExecutor should have HttpWebRequest should have KeepAlive = true as it looks like HttpCommandExecutor is running stateless commands. Maybe you can consider to remove the passing in of the attribute to avoid future problem.

This PR makes the Selenium WebDriver project compile on .NET Core. The changes basically boil down to fixes for:

• The new reflection API
• The absence of Serialization
• Standardization on .Dispose instead of .Close
• Changes in how OS-related information is accessed
• Changes in the HttpWebRequest and HttpWebResponse classes

Happy to work with you on any feedback you may provide,

What happened?

after updating selenium WebDriver (3.15 to 4.0.0) and IEDriver (3.150.1 to 4.0.0) getting below error while setting dropdown value, code was working properly with old selenium version (3): Error : Cannot click on option element. Executing JavaScript click function returned an unexpected error, but no error could be returned from Internet Explorer's JavaScript engine

HTML :

C# code : public By countrySelector = By.Id("selCountry"); public string Country { set => new SelectElement(Driver.FindElement(countrySelector )).SelectByText(value); }

   Country= "India";

How can we reproduce the issue?

HTML : 
<TD vAlign=top><SELECT id=selCountry">
<OPTION selected value=0>None</OPTION> <OPTION value=1>India</OPTION></SELECT>
</TD>
       

 public By countrySelector = By.Id("selCountry");

        public string Country
        {
            set => new SelectElement(Driver.FindElement(countrySelector )).SelectByText(value);
        }

Country= "India";

I've been gradually trying to push support of shadow DOM v1 into selenium (see #4230, #5762).

However, we are still missing one major piece: traversal.

There needs to be some ability to traverse shadow DOM when calling FindElement and what not.

So maybe we can discuss some possible implementations here?

What we can't/shouldn't do:

• Alter how existing selectors work (CSS, XPath, etc. they should all behave as they do now)
• Implement deprecated things like /deep/
• Implement our own selector syntax/mechanism

The way I see this working is that we should treat the DOM as we would in the browser, meaning there will not be a way to select a deep element in one call:

element
  .FindElement(By.CssSelector("foo"))
  .ShadowRoot?
  .FindElement(By.CssSelector("bar"));

Which, in the browser, would be structured the same (no shortcuts):

element
  .querySelector('foo')
  .shadowRoot
  .querySelector('bar');

So maybe we just need to implement ShadowRoot on WebElement? Which can be null (just like in the browser).

Meta -

OS: OSX Selenium Version: 3.8.1 Browser: Chrome

Expected Behavior -

Permit files to be downloaded in headless mode.

Actual Behavior -

Files aren't downloaded.

Steps to reproduce -

Launch chrome in headless mode and try to download any file.

Looks like it is a feature to prevent sites from downloading files when running chrome in headless mode. https://bugs.chromium.org/p/chromium/issues/detail?id=696481

To permit downloads it's necessary to send a command to chrome. I'm using java and I couldn't find a way to make it work.

I even tried sending a post request to /session/:sessionId/chromium/send_command but that didn't work.

What happened?

We are seeing ZScaler login prompts during our test execution where we previously did not. We have confirmed that the browser session already had a valid ZScaler token when it was prompted. Unsure how to troubleshoot this further to identify the issue or if there is a misconfiguration with our proxy settings that's causing this.

How can we reproduce the issue?

Feature and motivation

Java currently adds links to our documentation for various error messages (https://github.com/SeleniumHQ/selenium/blob/selenium-4.7.0/java/src/org/openqa/selenium/WebDriverException.java#L78)

We should add basic descriptions for all of the errors in our docs, and we should add links to these in all of the bindings.
